Surpise my 4 kids with a vacation

I have four wonderful kids. They don't know what a vacation is. the feeling when your ears pop as a plane flies up I feel Disney land maybe fun, it isn't cost effective. I would love to take them on an all inclusive trip. I want them to be able to feel the ocean move their bodies as they swim. I would love to see their toes running through white sandy beaches and make sandcastles. I want us to see and go somewhere that has wonderful history with tours that teaches them. Their dad hasn't seen or spoken to them in about three years and they receive no child support. We are so grateful we have this experience to live on the farm. Learning so many things. I went from Chicago to here and learned that country life fits me. Honestly, we have been through a lot and don't do very much. I would just LOVE this to happen. I know their are others that have more important needs. Our need is different. We need a break. I need to show them that there are so many cool things out in this world to experience. I want to see the looks on their faces as they get on a plane to a destination unknown. An experience they will remember. Thank you all.
